[javier vera]

Summary of the bug:
Error message:
Cannot find a matching stream for unlabeled input pad extrastereo:default
Error binding filtergraph inputs/outputs: Invalid argument

How to reproduce:
(A simple code i was using for years, to apply extrastereo to video)

ffmpeg -i C:\Pelis\video.mkv -vcodec copy -map 0:a -map 0:v -acodec aac -b:a 384k -ac 2 -filter_complex extrastereo C:\Pelis\Salida.mkv

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker

the operative system is windows 11 23h2 and the last version avariable of ffmpeg.
The problem was comming after update my older version of ffmpeg 5

The problem was the new syntax from FFMPEG

For work correctly need change code from:
ffmpeg -i C:\Pelis\video.mkv -vcodec copy -map 0:a -map 0:v -acodec aac -b:a 384k -ac 2 -filter_complex extrastereo C:\Pelis\Salida.mkv

To:
ffmpeg -i C:\Pelis\video.mkv -map 0:v:0 -c:v copy -acodec aac -b:a 384k -ac 2 -filter_complex extrastereo C:\Pelis\Salida.mkv

That types of changes be goodto be reflex in the documentation of the wiki. Thanks i close the bug report
